You have to make sure you have a confirmation created. Actually, if you do it in the goods movement screen of the confirmation all you have to do is add a line make the movement 551 and provide a reason.

In this case I want to follow the process for unplanned scrap. I'm trying to do that you mentioned, I entered on MIGO and then selected Good Issue / put the order Order and type 551 as movement however, I'm getting the message "Document 000503849497 does not contain any selectable items" and is the same message with any production order.
